Water Softener

Setting up the Water Softener

Only some models (those with a letter ‘H’ in the model name) have a built-in water softener.
Models with water softener are not currently available in New Zealand and Australia.

Determine the Water Hardness in your Local Area

Your local water company will be able to provide you with information. Identify the setting you require for your dishwasher from the water hardness table below. For example, if your water hardness is 500 ppm, then the water softener setting on your dishwasher should be 4. Refer to the ‘Preference options’ section of your ‘Quick start guide’ for instructions on adjusting the water softener setting.

If your water hardness is above 625 ppm/36 gpg, we highly recommend you completely fill the detergent dispenser for all programs except Rinse and the rinse aid setting should be at 5. If your water hardness is above 625 ppm/36 gpg, the wash performance of your dishwasher will decline.

You may hear some unusual noises when the water softener is in operation, this is normal.

How to Fill the Salt Reservoir

Open the drawer(s).

Unscrew the salt reservoir cap by turning anticlockwise.

Place the salt into the salt container and pour the contents into the salt reservoir.
The salt reservoir can hold up to approximately 1 lb/0.5 kg of salt.

Fit the cap tightly back into its original position.

If you do not wash your dishes immediately after filling the salt reservoir, run a Rinse program to remove any salt water or spilt granules.

When filling the salt reservoir, you may notice water being displaced from the water softener overflow.

The water softener must always be filled with granular salt made especially for dishwasher water softening systems. We do not recommend the use of cooking salt like table salt, rock salt or pellets as they may contain impurities that will impair or diminish the life of the water softener.

The Salt Reservoir

Water softening can only take place when there is salt in the reservoir. The salt reservoir must be filled prior to using the dishwasher and whenever the salt indicator light is red.

Salt Indicator Light

If the salt indicator light is red, the salt reservoir is empty.

If the salt indicator light is black, there is enough salt in the reservoir for the wash program that has been selected.

Classic models only: The electronic display will also indicate when the salt reservoir is empty by displaying the salt symbol.

Do not pour detergent or rinse aid into the salt reservoir. Detergent and rinse aid will destroy the water softener.
